“…Mareš et al (2007) tested three dry diets with 7 month-old juveniles (0.8-1.2 g) during 63 days, and FCRs ranged from 1.84 to 4.15. The FCRs obtained in the present study ranged from 1.35 to 1.57 and were similar to the reported by González- Rodríguez et al (2013) starting also with 5 month-old juveniles and using the same basal diet. In both cases, values are more favorable than those previously reported and are close to the feed conversion rates in the intensive culture of well studied species, with values typically ranging from 0.8 to 1.5 (Hardy and Barrows, 2002).…”

The aim of this study was to evaluate different replacement levels of fish meal (FM) by soy protein concentrate (SPC) on survival, growth performance and body composition of juvenile tench (Tinca tinca). A 90-day experiment was conducted with 5 month-old juveniles (31.95 mm total length, 0.396 g weight). Eight practical diets (50% crude protein) differing in the level of replacement of FM protein by SPC protein were tested: 0% (control diet), 25%, 35%, 45%, 55%, 65%, 75% or 100% corresponding to 0, 159, 222, 285, 348, 412, 475 or 634 g SPC kg -1 diet, respectively. Survival rate was 100% for all diets. Significant differences were not found (P>0.05) in growth values among 25%, 35% or 45% replacement diets and the control diet. At higher replacement levels (from 55% to 100%), fish had significantly lower growth (P<0.05). Fish fed from 0% to 45% replacement diets had significantly lower (P<0.05) feed conversion ratio and higher (P<0.05) protein productive value than those fed diets with higher replacement levels. The percentages of fish with externally visible deformities ranged from 1.1% to 4.4%. The relation among amino acid profiles of the diets, body composition, growth performance of juveniles and amino acid requirements of other fish species are discussed. Up to 285 g SPC kg -1 diet can be included in diets for juvenile tench without impairing growth performance.

“…Based on the practical diet proposed by González- Rodríguez et al (2013) Table 2 and amino acid profiles are in Table 3. Fish were fed manually four times a day (at 10: 00 , 14: 00 , 18: 00 and 22: 00 hours) to apparent satiation.…”

“…However, growth of tench often remains slow under controlled conditions (Sierra, Sáez‐Royuela, Carral, Celada, Gaudioso, Muñoz & Pérez ; Wolnicki & Myszkowski ). Moreover, highly intensive feeding of tench juveniles with a dry diet frequently results in the occurrence of body deformities (Wolnicki, Kamiński & Myszkowski ; Wolnicki ; Kamler, Myszkowski, Kamiński, Korwin‐Kossakowski & Wolnicki ; Wolnicki, Myszkowski, Korwin‐Kossakowski, Kamiński & Stanny ; Celada, Aguilera, García, Carral, Sáez‐Royuela, González & González ; García, Celada, Carral, Sáez‐Royuela, González & González ; Myszkowski, Kamler & Kwiatkowski ; González‐Rodríguez, Celada, Carral, Sáez‐Royuela & Fuertes ). Appearance of body deformities in high share of fish in aquaculture is unacceptable because of economic concerns and fish welfare.…”

Diet and water temperature affect growth and body deformities in juvenile tenchTinca tinca(L.) reared under controlled conditions

The experiment was designed to determine the combined effect of fish diet and water temperature on juvenile tench Tinca tinca (L.). Three diets were used: commercial dry diet for fish Aller Futura (diet F); frozen Chironomidae larvae (diet C); and Aller Futura substituted with Chironomidae at a ratio of 3:2 (dry weight; diet FC). Daily food rations and duration of the experiment were adjusted to temperatures of 20°C, 23°C and 26°C based on a correction factor q equal to 1.000, 0.779 and 0.609 respectively. The experiment lasted 92, 72 and 56 days for the respective temperatures. No mortality occurred. The highest relative growth rates were found at 26°C in diets F and FC. The lowest food conversion ratio of 1.12-1.22 (recalculated for dry weight of feed diet) was determined in fish fed diet F at 23°C and 26°C. A high value of condition index appeared to be the early warning of decreasing biological quality of fish and deformities. The lowest incidence of fish with deformities (IDef) was found in groups fed diet C (<1%), while the highest (90%) in fish fed diet F at 26°C. A lower share of dry diet in the fish food and a lower water temperature led to a lower IDef. Thus, amount of dry feed in fish diet was the major factor inducing body deformities, while water temperature only modified the effects of the dietary factor. Diet C at 23-26°C was the most cost-effective of the tested combinations of diet and temperature.

“…Recently, the tendency of intensive aquaculture to produce fish of low biological quality, including those with body deformities, has become a problem of major importance (Witten et al 2009, Boglione et al 2013a, 2013b. In tench, an increasingly important aquaculture species, this problem is very common (Rennert et al 2003, Kamler et al 2006, Celada et al 2009, García et al 2010, González-Rodríguez et al 2014.…”

Kamiński R., Sikorska J., Polak-Juszczak L., Wolnicki J. 2017. Effects of temperature on body chemical composition and incidence of deformities in juvenile tench, Tinca tinca (Actinopterygii: Cypriniformes: Cyprinidae), fed a commercial dry diet and/or natural food. Acta Ichthyol. Piscat. 47 (1): 63-71.Background. Water temperature is a major factor regulating fish metabolism. It can influence body chemical composition and the incidence of body deformities. The latter often develop in farmed fish and this issue is currently emerging as a serious problem for aquaculture. Determining the effects of water temperature on body chemical composition and fish body deformities is an important subject for research in fish biology and nutrition, and aquaculture. The presently reported study was conducted using juvenile tench, Tinca tinca (Linnaeus, 1758), an important aquaculture species in Europe. Two hypotheses were tested: 1) temperature can significantly influence body chemical composition and the incidence of body deformities in fish; 2) the effects of temperature on fish depend on their diet. Material and methods. Fish, with an initial total length of 28.4 ± 2.7 mm and body weight of 0.24 ± 0.07 g, were reared at 20, 23, and 26°C and fed dry feed Aller Futura (Aller Aqua, Denmark) only, or a combination of this feed and natural food (frozen larvae of Chironomidae) in a 3 ÷ 2 ratio of dry matter, or the natural food alone. The duration of the experiment and the daily food rations were adjusted to the experimental temperatures based on a correction factor, q, of 1.000, 0.779, or 0.609, respectively. The experiment duration was 92, 72, or 56 days for the respective temperatures.Results. Body deformities occurred in all groups of fish fed solely or partially with the dry diet (21.5%-89.5%). The incidence of deformities was directly proportional to the temperature and the content of dry feed in the diet reaching the maximum in fish fed exclusively the dry diet at 26°C. Water temperature and fish diet influenced body chemical parameters (moisture, protein, lipid, ash, Ca, P, Mg, Ca ÷ P, Mg ÷ P), but water temperature did not have a significant effect on whole-body P content. Conclusions. Water temperature proved to significantly influence fish chemical body composition and the incidence of body deformities in fish fed dry diet. The major factor that caused fish P deficiency, and resulted in low body ash content and body deformities, was insufficient bioavailability of P in the dry diet. Water temperature appeared to only modify P deficiency symptoms in fish. Keywords: fish, food utilization, growth, nutrition, phosphorus INTRODUCTIONWater temperature is a major factor regulating fish metabolic rates, energy expenditure, food intake, and nutritional efficiency. Metabolic rate increases exponentially with temperature, and, at any given temperature, the difference between the energy gained by fish via food intake and the energy consumption by metabolism determines the resources available for growth (Brett and Groves 1979).
